Hi @mailtocprakash, please check that you have enough free memory on the machine where the agent is running.
If you use large repositories you could try shallow fetch.
In some cases might help to enable option FIX_POSSIBLE_GIT_OUT_OF_MEMORY_PROBLEM variable, if the option is enabled, mingit 2.42.0.2 will be used instead of the 2.39.1.

I have unzipped the agent in C: drive in Azure VM, where it has 114 GB free space is available and my git repo size is 20 MB only.

Can you elaborate how to set the [FIX_POSSIBLE_GIT_OUT_OF_MEMORY_PROBLEM ] variable in sel-hosted agent VM machine? or in pipeline ?

[DmitriiBobreshev]

@mailtocprakash, the error says that you don't have enough free RAM. How much free RAM do you have after the agent is running?
You can set FIX_POSSIBLE_GIT_OUT_OF_MEMORY_PROBLEM as a Pipeline variable or as os env variable

Increased the size of the VM from 1 GB RAM to 4 GB RAM, Now Git fetch started working.

Thanks a lot @DmitriiBobreshev
